Chain saw attack targets homeless

A man wielding a chain saw and a knife attacked residents at a homeless shelter where he was staying, leaving two people in critical condition and injuring two others, police said.

Matthew Watkins, 28, was charged with four counts each of first-degree assault and armed criminal action for the attack Saturday at the Mid-America Care Center, the Callaway County Sheriff's Office said.

Sheriff Dennis Crane said two victims were cut by a chain saw and two others by a knife. Authorities said the victims injured by the chain saw were in critical condition, but the other two were treated and released.
